(JavaScript) GeneratorModule: Array Creation Inspired by Python\'s List Comprehension - codernator

Thu, 27 Dec 2012 06:11:03 GMT

The inspiration for this module comes from Python's list comprehension: [x for x in range(10)]. The idea is to replace a for-loop with something more condensed. However, since such syntax is completely foreign to Javascript, that operation looks more like: app.genList(app.rangeGenerator(0, 10)). Requires ObjectBoilerPlateModule. GeneratorModule comes with four "public" methods: * getGeneratorModuleVersion - useful to test for existence of module. * arrayGenerator - iterate over an array, optionally filtering items from the array with a predicate argument. * rangeGenerator - iterate over a number sequence from min to max. * genList - create an array using either an arrayGenerator or a rangeGenerator, optionally morphing elements from the generator into a new data type. This is implemented using module pattern. To inject the functions into the global namespace, simply invoke the GeneratorModule method. Otherwise, the functions can be added to an existing object using GeneratorModule.call([object]). Examples: function test() { "use strict"; function reportNumber(number) { return number + " is " + (number % 2 === 0 ? "even" : "odd") + "."; } function reportLetter(letter) { return "The letter is " + letter + "."; } function isMultipleOf3(number) { return number % 3 === 0; } var app = {}; ObjectBoilerPlateModule.call(app); GeneratorModule.call(app, app); console.log(app.toList(app.range(0, 10))); // [0,1,2,3,4,5,6,7,8,9] console.log(app.toList(reportNumber, app.range(0, 15), isMultipleOf3)); // ["0 is even.", "3 is odd.", "6 is even.", "9 is odd.", "12 is even."] console.log(app.toList(app.inArray(["a", "d", 'q']))); // ["a", "d", "q"] console.log(app.toList(reportLetter, app.inArray(["a", "d", 'q']), function (x) { return x === "a"; })); // ["The letter is a."] } Limitations/Considerations: * Like Python generators, only 1 iteration will function - the generators do not come with a "reset" method. * The ArrayGenerator objects hold reference to "list" passed in the constructor. If there is code between creating the generator and invoking it (say with genList), it is possible the contents of "list" will change. (This could be mitigated by having the ArrayGenerator constructor perform a deep copy "list"...)

(JavaScript) Get DOM element via class and id selector, using Google Closure - cjcenizal

Tue, 31 Jan 2012 15:00:26 GMT

The Google Closure lets you get DOM elements with getElement( id ) and getElementByClass( class ). This function combines the two to let you get elements similarly to the way jQuery does. E.g. getElement( '#home .sidebar #links') returns the element with an id of 'links', within the element of class 'sidebar', within the element of id 'home'.

(JavaScript) using unobtrusive namespace - coprolit

Mon, 21 Mar 2011 23:57:37 GMT

Unobtrusive JavaScript should add as little as possible to the global object or global namespace of the environment in which it runs. With following solution each module-writer's code is contained in private or in a unique namespace and cannot interfere with or intrude upon any other code at any time.

(JavaScript) Using params with setTimeOut - coprolit

Sat, 19 Mar 2011 01:38:02 GMT

With setTimeOut a reference to a function object cannot provide parameters for the scheduled execution of that function. We can instead use a closure to provide parameters for the execution of a function prior to the execution of that function.

(Groovy) Closure memoization in Groovy - narkisr

Tue, 11 Aug 2009 11:15:43 GMT

This example shows how its possible to cache (memoization) a Closure value, note that this works only for a single value per each delay method call (the Closure creates a closed scope in which its "state" is kept).
